Ya what Kem said. Try disconnecting it at night right after running it and the batt is charged. If it starts in the morning you have an amp drain. Under stand that this will reset the computer and the clock will need reset as well. But will not harm the system. Watch for an arc when reconnecting with no dome light or anything on as this is a sure sign of a current draw. This test will be no different than changing the batt so it can't harm the system. If done properly.

Friend of mine had an older Ford car that did the same thing. Dead every morning. We disconnected one battery lead and put a meter, in current mode, in series between the battery and the lifted lead. He had a three amp draw with everything off. We started unplugging things until the draw went away. In his case, is was a bad voltage regulator on the fender wall. Replaced it and all was well.
Good thing it was only three amps as my meter has a five amp fuse.
